The law that the induced e.m.f. and current always oppose the cause producing them is due to:a.Newtonb.Coulombc.Lenzd.Faraday

Identifying the Correct Answer

1. Understanding the Question: The question asks for the law that describes how induced electromotive force (e.m.f.) and current oppose the action that causes them. This is a fundamental concept in electromagnetism.

2. Evaluating the Options:

   • a. Newton: Primarily known for his laws of motion and universal gravitation, not specifically related to electromagnetism.
   • b. Coulomb: Known for Coulomb's law, which deals with electric forces between charged particles, but not directly related to the opposition of induced current.
   • c. Lenz: Formulated Lenz's Law, which states that the direction of induced current will oppose the change in magnetic flux that produced it.
   • d. Faraday: Known for Faraday's Law of Electromagnetic Induction, which describes how a changing magnetic field can induce an e.m.f., but does not specifically mention opposition.

3. Conclusion: Based on the evaluation, Lenz is the scientist who formulated the law specifically stating that the induced current opposes the change that caused it.

Final Answer

The law that the induced e.m.f. and current always oppose the cause producing them is due to c. Lenz.
